Re: [PATCH 3/3] advice: allow disabling the automatic hint in advise_if_enabled()

> Using advise_if_enabled() to display an advice will automatically
> include instructions on how to disable the advice, along with the
> main advice:
>
> 	hint: use --reapply-cherry-picks to include skipped commits
> 	hint: Disable this message with "git config advice.skippedCherryPicks false"
>
> This can become distracting or noisy over time, while the user may
> still want to receive the main advice.
>
> Let's have a switch to allow disabling this automatic advice.
